Every time somebody buys a Gatorade, the University of Florida gets a cut. It has added up to more than $500 million. And it all started because a football coach asked a kidney doctor why his players were not going to the bathroom. Here is the whole thing. It was the summer the Florida Gators were melting in the heat. Players were landing in the infirmary with heat exhaustion. Guys were losing as much as 18 pounds in a single game. An assistant coach named Dwayne Douglas took the problem to a doctor at the university named Robert Cade. A kidney specialist. His question was simple. He wanted to know why his players were losing all that weight and barely going to the bathroom. Cade figured it out fast. They were sweating so much there was nothing left. So he and his team tested 10 freshman players. Their blood sugar was low. Their fluids were low. Everything their bodies needed was pouring out of them. Cade went to work on a drink. Water, salt, sugar, a few other things. The first batch tasted so bad that none of the doctors could get it down. His wife, Mary, had an idea. Add lemon juice. Head coach Ray Graves would not risk his varsity on it. He gave them the freshmen. So the freshmen got the drink in a scrimmage against the varsity B team. The B team led 13 to 0 at halftime. In the second half the freshmen ran them off the field. Graves wanted it for the varsity. Right now. The next day Florida played the LSU Tigers in 102 degree heat. The doctors stayed up all night mixing 25 gallons. LSU wilted in the fourth quarter. Florida won 14 to 7. They became known as a second half team. A little over a year later they played the Georgia Tech Yellow Jackets in the Orange Bowl and won 27 to 12. Georgia Tech's coach, Bobby Dodd, was asked what happened. "We didn't have Gatorade." They named it after the team. Today it is everywhere. It is on every sideline, and coaches get it dumped on their heads after wins. Here is the honest part. Gatorade did not win all those games by itself. Florida also had Steve Spurrier at quarterback, and he won the Heisman Trophy that season. Cade liked to point out one funny thing about Florida's Heisman winner. "He drank Coca-Cola." Cade passed away at 80. He spent the rest of his career at Florida, still teaching and still seeing patients into his 70s. And the money from that one question is still pouring in. Florida has put it into cancer research, startups, sea turtle conservation and cooler football pads. All because a coach wanted to know why his players were not going to the bathroom.
